1.0 INTRODUCTION AND PROJECT DESCRIPTION In February 2005, 806026 Alberta Ltd., as a General Partner of Duke Energy Field Services Canada L.P., a wholly owned subsidiary of Duke Energy Field Services Canada Ltd. (Duke), received the National Energy Board (NEB) Order XG-Z007-03-2005, pursuant to Section 58 of the NEB Act that granted approval for the construction of the Pesh Creek Pipeline Loop (the Project). In June 2009, Spectra Energy Transmission (Spectra), formerly Duke, was granted a variance to Condition 7 and Amending Order AO-5-XG-Z007-03-2005 was issued.
The Project consisted of the construction of approximately 16.5 km of 273.1 mm O.D. (NPS 4) sweet natural gas pipeline crossing the Alberta/British Columbia (BC) border approximately 100 km northwest of Rainbow Lake, Alberta and 160 km northeast of Fort Nelson, BC (Figure 1). The pipeline transports sweet natural gas from the existing Spectra Peggo gas processing facility in d-83-C/94-P-08 in northeastern BC, to the existing Nova Gas Transmission Ltd. (NGTL) Shekilie River North meter station at 10-04-119-12 W6M in northwestern Alberta.
The Pesh Creek Pipeline Loop was installed within a 20 m wide right-of-way, of which 5 m was shared with the existing Pesh Creek Pipeline right-of-way for 100% of its length. The existing Pesh Creek Pipeline was approved under NEB order GH-1-96. Additional temporary workspace was acquired where necessary for soils and slash handling at tie-ins as well as at crossing of watercourses and foreign pipelines. Aboveground facilities required for the operation of the pipelines included pipeline risers, valves, pig launcher/receiver and tie-in piping only, as sufficient capacity already existed at the NGTL meter station. Construction began on February 25, 2005 and was completed on April 12, 2005.
Spectra has committed to Post-Construction Environmental Monitoring (PCEM) of the right-of-way during the first and second complete growing seasons following construction. Spectra requested and received approval from the NEB to defer the commencement of PCEM until the 2009 growing season, due to delays in final clean-up of subsided areas along the pipeline right-of-way and ongoing delays in securing borrow pit soil for use in reclamation activities. This report presents the results of the first year PCEM program conducted on August 25, 2009.

2.0 ENVIRONMENTAL SETTING The Project route traverses forested Crown lands on level terrain within the Wetland Mixedwood Subregion of the Boreal Forest Natural Region in Alberta and the Boreal White Spruce Biogeoclimatic Zone in British Columbia (TERA Environmental Consultants [TERA] 2005a). Vegetation along the route ranges from black spruce muskeg with scattered tamarack on poorly-drained land at the west end of the route, to more upland, moderately to well-drained trembling aspen forest with scattered white and black spruce at the east end of the route.
The Alberta portion of the pipeline route lies within the Cameron Hills Uplands section of the Northern Alberta Uplands Physiographic Region. The BC portion of the pipeline route lies within the Great Plains Physiographic Region.
The forested lands traversed by the pipeline are deemed to have no agricultural capability. These lands consist of organic cryosolic soils located on a morainal till layer of clay and cobbley sand and gravel directly overlying bedrock within the southern fringe of the discontinuous permafrost zone.
The pipeline route traverses five watercourses, including the Shekilie River; all five are located in BC.

3.0 MONITORING PROGRAMS A number of environmental monitoring procedures will be implemented by Spectra with the objectives of identifying potential or existing environmental issues and recommending, where warranted, remedial measures to address any outstanding environmental impacts. These procedures include: environmental monitoring during construction; frequent aerial line patrols; monitoring and pipeline right-of-way maintenance by the operations department following construction; and a third-party PCEM program.
3.1 Construction Monitoring
Environmental issues were monitored during construction to ensure that environmental protection measures were implemented and that the protection measures were effective in minimizing environmental impacts. An Environmental Inspector was assigned to the construction program to monitor all phases of construction, with particular emphasis on issues and activities which were considered to have the greatest potential for environmental impact.
3.2 Operational Monitoring
Operational monitoring includes regular aerial line patrols of the entire pipeline system. Any problem sites are noted during the patrols and corrective action is taken where necessary.
3.3 Environmental Issues Monitoring
A first year environmental issues monitoring program was undertaken during the summer of 2009 to examine any unresolved environmental issues and to identify any new issues related to reclamation. The purpose of the PCEM is to:
• evaluate the recovery of areas disturbed during pipeline construction;
• assess the status of outstanding environmental issues identified in the Environmental and Socio-Economic Assessment (ESA) (TERA 2005a) and the Environmental As-Built Report (TERA 2005b);
• identify any new environmental issues that may have arisen;
• visually inspect the right-of-way via late summer aerial reconnaissance for known, as well as previously unidentified environmental issues;
• recommend remedial measures to be implemented to address outstanding environmental issues in a timely manner; and
• update the Environmental Issues List (EIL) upon completion of the late summer aerial reconnaissance whereby the final EIL from the first year PCEM Report will provide the starting point for the second year PCEM program.
An aerial reconnaissance was conducted by TERA personnel in late August 2009.

4.0 PCEM METHODOLOGY The methodology for monitoring the status of environmental issues is based on the philosophy, and with the fundamental principle, that the success of land reclamation is measured against the representative (i.e., adjacent) site conditions with due consideration for construction norms at the time of the assessment. Where no known limitations to normal management and ecosystem function for that land type are evident during the PCEM, mitigative measures will be determined to be successful and the environmental issue resolved.
4.1 Preliminary Work
Preliminary work included a review of potential environmental issues as determined from the ESA, applicable construction documents (e.g., Environmental As-Built Report) and any other documentation of issues that were encountered during construction.
4.2 Aerial Reconnaissance
The aerial reconnaissance was scheduled to be conducted in late summer, when vegetation is mature enough for accurate identification and evaluation. A Reclamation Specialist was assigned to conduct the aerial reconnaissance of the entire pipeline construction right-of-way by helicopter to identify any additional locations warranting further monitoring (Appendix A). Parameters assessed during the aerial reconnaissance include slope movement, trench settlement, deterioration of erosion control devices, revegetation failures, improper waste or debris disposal and weed infestations.

5.0 RESULTS/OBSERVATIONS An EIL was compiled from the Environmental As-Built Report for the Project and was reviewed prior to the late summer PCEM (Appendix B). This list provides a summary of potential environmental issues along the right-of-way prior to pipeline construction, clean-up and reclamation. Following the fieldwork, the EIL was updated (Table 1) to provide the current status of environmental issues and the mitigative measures planned to address unresolved issues.
During the aerial reconnaissance, it was observed that the pipeline right-of-way is recovering well, and that shrubs and grasses are successfully establishing along much of the right-of-way. A typical view of the right-of-way is provided in Plate 1. The following is a description of all unresolved environmental issues and the proposed mitigative measures to resolve these issues.

ENVIRONMENTAL ISSUES LIST
Environmental Issues Location Mitigative Measures and Observations in 2009 Status Recommendations 1. PHYSICAL ENVIRONMENT (a) fill/backfill instability Entire route • During the 2009 PCEM, subsidence was observed
from KP 3.3 to KP 3.8. Unresolved Repair and continue
monitoring for trench subsidence and for excessive crown loss causing altered drainage patterns and recontour where necessary.
2. WATER QUALITY AND QUANTITY (a) Alterations of natural
flow patterns Entire route • During the 2009 PCEM, subsidence was observed
from KP 3.3 to KP 3.8. Unresolved Repair and continue
monitoring for trench subsidence and for excessive crown loss causing altered drainage patterns and recontour where necessary.
3. WETLANDS (a) loss of wetland habitat Entire route • Wetlands are naturally regenerating following
construction. • During the 2009 PCEM, low-lying areas along the
right-of-way were observed to be consistent with preconstruction drainage contours.
Resolved None.
4. VEGETATION (a) Loss or alteration of
native vegetation and vegetation important to wildlife
Entire route • Areas of poor growth were noted from KP 0.0 to KP 1.6 along the pipeline route during the 2009 PCEM; however, vegetation establishment generally appears successful along the right-of-way.
Unresolved Broadcast seed with an approved native seed mix from KP 0.0 to KP 1.6. Continue monitoring the establishment of native vegetation. Control trees and shrubs, if necessary, to facilitate pipeline surveillance, by mechanical rather than chemical means.
(b) Weed introduction and spread
Entire route • No weeds of concern were identified during the 2009 PCEM program.
Unresolved Continue monitoring for weed growth and introduction.
5. WILDLIFE AND WILDLIFE HABITAT (a) Loss or alteration of
potential wildlife habitat
Entire route − See Vegetation element. Unresolved See Vegetation element.
5.1 Physical Environment
5.1.1 Fill / Backfill Instability
During the 2009 PCEM, subsidence was observed from KP 3.3 to KP 3.8 along the pipeline right-of-way (Plates 2 and 3). The remainder of the pipeline route appeared stable and no trench line settlement was observed. Repair of subsided areas along the right-of-way and continued monitoring of trench settlement and subsidence in 2010 along the entire right-of-way is recommended.

5.2 Water Quality and Quantity
5.2.1 Alterations of Natural Flow Patterns
Trench line subsidence occurring along the pipeline right-of-way potentially interferes with natural drainage patterns and may also lead to impeded cross drainage across right-of-way. Monitoring of the right-of-way in 2010 is recommended to ensure that any regraded trench line along the route has settled but not subsided.
5.3 Vegetation
5.3.1 Loss or Alteration of Native Vegetation and Vegetation Important to Wildlife
Vegetation along the length of the pipeline right-of-way in Alberta and BC is recovering naturally, and low-growing shrubs and grasses were observed along most of the right-of-way during the aerial reconnaissance. Areas of poor growth were noted from KP 0.0 to KP 1.6 (Plates 4 and 5). Broadcast seeding along areas of poor growth from KP 0.0 to KP 1.6 with an approved native seed mix from KP 0.0 to KP 1.6 may be warranted. It is also recommended that the right-of-way be monitored in 2010 to ensure that the natural revegetation is providing adequate ground cover along the right-of-way and to monitor the establishment of grasses and ground cover along any areas of recontoured trench line.
5.3.2 Weed Introduction and Spread
During the 2009 PCEM, no weeds of concern were identified. Continued monitoring of the right-of-way for weed problem areas is recommended. The use of chemical control is not recommended for any trace to moderate densities of weeds occurring along the pipeline route. Successful revegetation occurring along the right-of-way appears to be currently outcompeting and preventing weed infestations.

6.0 CONCLUSIONS AND RECOMMENDATIONS The results of the 2009 PCEM indicate that a high standard of environmental protection was achieved throughout the construction program. Environmental issues were immediately resolved when possible. The few outstanding issues identified in the EIL will continue to be monitored and the necessary actions taken until all issues are resolved.
The entire length of the right-of-way will be inspected during the 2010 growing season and will primarily assess the outstanding issues of trench and crown settlement and revegetation success along the right-of-way.

2. Bracketed numbers refer to corresponding sections in the EPRP text where more complete instructions are provided. Additional environmental protection measures are outlined in Sections 2.0 to 14.0 in the EPRP text.3. Avoid constructing during excessively wet or thawed conditions (3.0). Rip compacted subsoils to a depth of 30 cm or the depth of compaction, whichever is deeper. If soils are thawed, postpone ripping of subsoils until soils refreeze (10.0).4. In low-lying wet areas, walk frost in on work side (6.0). Retain nonmerchantable timber, where warranted, for use as corduroy (5.0).
Remove corduroy during clean-up.
5. Seed disturbed forested portions of the right-of-way with the appropriate seed mix.12. CLI (Canada Land Inventory) classes are described in Section 5.0 of the ESA.

ENVIRONMENTAL ISSUES LIST FROM THE ENVIRONMENTAL AS-BUILT REPORT FOR THE DUKE PESH CREEK PIPELINE LOOP
Environmental Issues Location Mitigative Measures Implemented During Construction Status Proposed Post-
Construction Measures 1. PHYSICAL ENVIRONMENT (a) fill/backfill
instability Entire route • Grading was minimized along the route with the pipeline loop
paralleling existing pipelines and temporary workspace occupying adjacent pipeline rights-of-way. Maximum grade width was approximately 12 m.
• Muskeg portions of the right-of-way were levelled and due to the slow and poor drainage of these areas, erosion control was not a concern.
• Backfilling operation was kept as close as possible to lowering-in activities.
• Due to the frozen condition of the soil, no trench compaction was done, and the excavated material was piled over the trench line in a crown.
Unresolved Monitor trench line settlement and right-of-way contours.
2. WATER QUANTITY AND QUALITY (a) alteration of
natural flow patterns
Entire route • The right-of-way was recontoured to restore the preconstruction grades and drainage contours.
• Breaks were left in the trench crown at obvious drainages to minimize interference with natural drainage.
Unresolved Identify areas of ephemeral drainage, ensure drainage patterns were maintained during reclamation and monitor trench line settlement.
3. WETLANDS (a) loss of wetland
habitat Entire route • Existing linear disturbances were paralleled to minimize the
amount of new disturbance along the pipeline right-of-way for 100% of its route.
• Construction occurred during frozen ground conditions. • The right-of-way was recontoured to restore the preconstruction
grades and drainage contours.
Unresolved Monitor wetland restoration.
4. VEGETATION (a) loss of vegetation
important to wildlife
Entire route • Minimal clearing (approximately 20 ha) was required as the right-of-way paralleled existing clearing for 100% of its route.
• Clearing was done with mulching machines and there was no burning of cleared woody debris.
• Existing pipeline rights-of-way were used for temporary workspace.
Unresolved Monitor the success of the revegetation program.
(b) weed introduction and spread
Entire route • All equipment arrived onsite clean of any debris. Unresolved Monitor right-of-way for weed problem areas.
5. WILDLIFE AND WILDLIFE HABITAT (a) loss or alteration
of potential wildlife habitat
Entire route • Minimal clearing (approximately 20 ha) was required as the right-of-way paralleled existing clearing for 100% of its route.
• A small amount of timber was left un-mulched but cleared in order to be used for habitat berms.
• Existing pipeline rights-of-way were used for temporary workspace.
• The right-of-way was recontoured to restore the preconstruction grades and drainage contours.
Unresolved Monitor the re-establishment of low-growing shrubs and grasses on the right-of-way.
(b) auditory or visual disturbances of wildlife
Entire route • Construction activities were completed by April 12, 2005. • Construction adhered to the Caribou Protection Plan filed with
Alberta Sustainable Resource Development.
Resolved None.
(c) mortality Entire route • Construction activities were completed by April 12, 2005. • Construction adhered to the Caribou Protection Plan filed with
Alberta Sustainable Resource Development.
Resolved None.
6. SPECIES AT RISK (a) auditory or visual
disturbances of wildlife species at risk
Entire route • See Wildlife and Wildlife Habitat element -- See Wildlife and Wildlife Habitat element.

Construction Measures (b) mortality of wildlife
species at risk Entire route • See Wildlife and Wildlife Habitat element -- See Wildlife and Wildlife
Habitat element. 7. HUMAN OCCUPANCY AND RESOURCE USE (a) disruption of other
resource based industries
Entire route • Forestry and other oil and gas companies were notified of the Project and construction schedule.
Resolved None.
(b) disruption of hunting and trapping activities
Entire route • Local trappers and outfitters were notified of the proposed Project and activity schedule prior to commencement of Project activities.
Resolved None.
8. ACCIDENTS AND MALFUNCTIONS (a) hydrocarbon spill
during construction or operation
Entire route • All spills were to be reported immediately to the Chief Inspector and, if warranted, appropriate government agencies.
Resolved None.
(b) rupture of foreign lines
Entire route • All foreign pipelines and existing buried utilities were exposed with hydrovac trucks prior to construction of the Project.
Resolved None.
